Does someone with congenital heart failure have a disorder?
I'm not suggesting that ADHD is on par with congenital heart failure, but neither are skin color or one's propensity towards wizardry on par with ADHD.
The point is that we shouldn't consider screwdrivers to be demented hammers even If you are a hammer like most in your surroundings.
If a game map is small (there is not much time for development before you are destroyed) and/or resource-poor then being Wizard is certainly a disadvantage compared to Necromancer (it is a "disorder", wizards are "demented" from the Necromancer's point of you).
Except humans are not primitive tools, and the brain is not a piece on a game board.
Perhaps a concept like CPU/GPU binning would be a bit more helpful to consider, but even then, it reduces one’s entire experience into manufacturing terms.
The worst CPUs are thrown in the trash. So are the broken hammers, and eventually the screwdriver misused as a hammer.
You are trying to reduce human mind to one bit: broken/working. Humans have strong general intelligence and therefore are capable of solving many different tasks. There are many different tasks in the world where different characteristics may be useful in addition to pounding nails (though if you are a hammer, it may be hard to imagine) The existence of screwdrivers shouldn't be considered a disorder.
